This image, by the Rosetta navigation camera, was taken from a distance of about 53 miles (86 kilometers) from the center of Comet 67P/Churyumov-Gerasimenko on March 14, 2015. The image has a resolution of 24 feet (7 meters) per pixel and is cropped and processed to bring out the details of the comet's activity.

This animation comprises 24 montages based on images acquired by the navigation camera on the European Space Agency's Rosetta spacecraft orbiting Comet 67P/Churyumov-Gerasimenko between Nov. 19 and Dec. 3, 2014.

During this period, Rosetta completed an almost full revolution at about 19 miles (30 kilometers) from the comet. These images were selected in such a way that their sequence appears to be continuous, a combined effect of Rosetta's motion with respect to the comet and the comet’s own rotation (every 12.4 hours).

This mosaic of images from the navigation camera on the European Space Agency's Rosetta spacecraft shows the nucleus of comet 67P/Churyumov-Gerasimenko as it appeared at in the early morning, Universal Coordinated Time, of Dec. 17, 2014 (evening of Dec. 16, Pacific Standard Time).

This mosaic of images from the navigation camera on the European Space Agency's Rosetta spacecraft shows the nucleus of comet 67P/Churyumov-Gerasimenko as it appeared at 5 a.m. UTC on Dec. 17, 2014 (9 p.m. PST on Dec. 16).

This composite is a mosaic comprising four individual NAVCAM images taken from 19 miles (31 kilometers) from the center of comet 67P/Churyumov-Gerasimenko on Nov. 20, 2014. The image resolution is 10 feet (3 meters) per pixel.

Four-image montage comprising images taken by Rosetta's navigation camera from a distance of 9.7 km from the centre of comet 67P/C-G – about 7.7 km from the surface. The corresponding image scale is about 65 cm/pixel, so each 1024 x 1024 pixel frame is about 665 m across.

Four-image mosaic comprising images taken by Rosetta's navigation camera from a distance of 9.8 km from the centre of comet 67P/C-G – about 7.8 km from the surface. The corresponding image scale is about 66 cm/pixel, and the mosaic covers roughly 1200 x 1350 metres.

Four-image montage comprises images taken by Rosetta's navigation camera from a distance of 9.8 km from the centre of comet 67P/C-G – about 7.8 km from the surface. The corresponding image scale is about 66 cm/pixel, so each 1024 x 1024 pixel frame is about 676 m across. In this orientation the larger lobe occupies the upper frames, with the neck filling the lower frames. The smaller lobe of the comet is out of view towards the right.
